Description
FIELD OF THE INVENTION
This invention relates generally to the combined camera and video cassette
recorder, and more particularly to the method for selecting mode by
utilizing one key in the wire remote controller, so that the function mode
of the camera recorder can be variously changed.
BACKGROUND OF THE INVENTION
Generally, the camera recorder which combines camera and video cassette
recorder is provided with the wire remote controller having the same
function as the release used in the still camera to prevent the set from
moving when pressing the function key attached at the set body for taking
a photograph.
The wire remote controller of the prior art is used when the camera
recorder is to be stopped temporarily during a recording function after a
temporary stop is performed. The recording and the temporary stop
functions (i.e. pause mode) are separated every time a key is pressed.
However, the conventional wire remote controller can not perform any other
functions excepting the recording and temporary stop functions, which is
shown in FIG. 1.
As shown in FIG. 1, the wire remote controller consists of a function Key
K1, a light emitting diode LED for displaying the recording state, and a
jack 10a.
The remote controller 10 is connected to a jack 20a of the camera recorder
20 by using the plug 10a at need, so that the camera recorder 20 receives
the input signal from the function Key K1, then performs the predetermined
operation in the circuit portion 20c of the camera recorder, thereby
driving the transistor Q1 by the output of the micro processor 20b.
That is, the conventional wire remote controller, performing only the
record and pause motions, is used by connecting the LED driving voltage,
the key input and the ground wires to the camera recorder 20 respectively.
In such a case, however, the wire remote controller is provided with each
function key so as to perform various functions such as reproduce (PLAY),
fast forward (FF), rewind (REW), standstill picture (STILL), etc. As a
result, it is required that the connecting wires connected to the plug 10a
to have anywhere from six to seven wires, not three.
Accordingly, the wire remote controller cannot be used to perform
multi-functions but can only be used to perform the recording and
temporary stop functions because the connecting wires are bulky in size
and the jack 10a and jack 20a has to be made by a special process.
In addition, the camera recorder is to be designed for performing a
multi-function using an integrated circuit, it can be expensive.
SUMMARY OF THE INVENTION
It is an object of this invention to provide a selecting mode method by
operating one key, so that it can select one of the various modes such as
PLAY, FF, REW, STILL, REC CHECK by operating one key while the existing
wire remote controller having three wires is used independently.
To achieve the above object, the present invention uses the first step for
changing the present mode into the temporary stop (pause), stop, record or
reproduce mode after reading the present mode when pressing the one key
one time; the second step for changing the present mode into the fast
forward mode or forward picture search mode after reading the present mode
state when pressing the one key two times; the third step for changing the
present mode into the rewind mode or reverse picture search mode after
reading the present mode when pressing the one key three times; and the
fourth step for changing the present mode into the standstill picture mode
or the record check mode after reading whether the one key is pressed the
predetermined time or more, and reading the present mode.
BRIEF DESCRIPTION OF THE DRAWINGS
In the detailed description of the preferred embodiment of the invention
presented below, reference is made to the accompanying drawings in which:
FIG. 1 is a schematic circuit diagram illustrating the camera recorder
connected with the conventional remote controller;
FIG. 2 is a timing chart for use in performing the mode selection method in
accordance with the present invention;
FIG. 3 is a mode changing table illustrating that the function of the
present mode is changed by effecting the mode selection method in
accordance with the present invention.
FIGS. 4A and 4B together show a flow chart illustrating an embodiment of
the mode selection method in accordance with the present invention.
The preferred embodiment of the camera recorder for performing the
multi-function mode by ultilizing the conventional wire remote controller
as it is, is illustrated in FIG. 1.
As shown in FIG. 1, after connecting the one-key three wire remote
controller to the camera recorder 20 through a plug 10a and a jack 20a,
the function key K1 is pushed. Thereupon, the selected function mode is
determined in the micro processor 20b, so that the transistor Q1 is
controlled by the micro processor 20b and the light emitting diode LED is
turned ON during the record mode and is turned off during the temporary
stop mode.
At this time, the micro processor 20b of the camera recorder 20 which
checks the pressing of the function key K1 of the controller 10, and
allows the light emitting diode LED to be turned on by driving the
transistor Q1, controls each function by controlling the circuit portion
20c of the camera recorder.
As mentioned above, according the present invention, the micro processor
20b recognizes the key input depending upon the pressing of the function
key K1 and determines mode to be changed depending upon the present mode.
The timing chart of the function by K1 is shown in FIG. 2 and the mode
changing table for changing the present mode into the predetermined mode
depending upon the input of the key is shown in FIG. 3.
Referring to FIG. 2, the input wave form signals a, b, and c of the key K1
by pressing one time, two times and three times respectively, within the
predermined time, and the input wave form signal d of the key K1 by
continuously pressing for a predetermined time or over are applied to the
micro processor so that the micro processor 20b determines whether the
function key K1 is pressed a number of times and how many times or is
pressed continuously for a predetermined time or longer.
The operation according to the FIG. 3 will be described with reference to
the flow chart shown in FIGS. 4A and 4B.
In the first step, micro processor 20b checks whether key K1 is pressed one
time or not.
If it is recognizes so, the 1A process for changing the present mode into
the temporary stop mode (PAUSE) is performed in the second step, and if
the present mode is the temporary stop mode, the 1B process for changing
it into the recording mode is performed in the fourth step.
In the sixth through eight steps if the present mode is the play mode, fast
forward mode or rewind mode, it is changed to the stop mode (the 1C
process), in the tenth through thirteenth steps if the present mode is
forward picture search (FPS) mode, reverse picture search (RPS) mode,
standstill (STILL) mode or stop mode it is changed to the reproducing mode
(the 1D process).
In addition, in the first step if the key K1 is not pressed one time or in
the fifth step if the key K1 is not pressed the predetermined N sec or
over it is read in the sixth step whether the key k1 is pressed two times.
When the micro processor 20b recognizes that the key k1 is pressed two
times in the sixteenth step, if the present steps of the seventeeth and
eighteenth modes are the stop or rewind mode, the 2A process which is for
changing into the fast forward mode is performed, and in the 20th and 21th
steps if the present mode is the reproducing or PRS mode, the 2B process
which is for changing to the FPS mode is performed.
Furthermore, if the key k1 is not pressed two times in the sixteenth step
or not pressed the predetermined sec or over in the 23th step, it is
readed whether the key k1 is pressed three times in the 24th step.
With the microprocess 20b recognizes that the key k1 is pressed three times
in the 24th step, if the present modes of the 25th and 26th steps are the
fast forward modes the 3A process which is for changing it into the rewind
mode is performed, while, if the present mode is the reproduce or FPS mode
in the 28th and 29th step, the 3B process which is for change it into RPS
is performed.
If, in the 24th step, the key K1 is not pressed three times, it is read in
the 31th step whether key K1 is processed at the predetermined N sec or
over.
At this time, when the key k, is pressed the predetermined n sec or over,
if the present mode of the 32nd step is the reproducing mode, the 4A
process which is for changing it into the standstill mode is performed,
and in the 34th step if the present mode is the temporary stop mode the 4B
process which for changing it into the record check mode is performed.
As stated above, the present invention provide the multi-function selecting
method by operating the one key of the wire remote controller, which can
simply perform the various functions by pressing the key of the wire
remote controller and without increasing the number of the connecting wire
of the wire remote controller.
